Comparison
Twine is fast, expressive, and deservedly influential. iepub is not trying to erase that. It serves a different priority: keeping the interactive work structured as a portable publication with a dedicated reader, a library flow, and an authoring tool built around export rather than only around editing.
Honest scope
If you want to improvise quickly in a single editor, Twine may remain the faster fit. If you want a stronger boundary between authoring, runtime, and publication, iepub becomes interesting. Variant is designed for drafting interactive fiction that can be previewed, exported, and then read in the same public ecosystem.
iepub keeps manifest, story, rules, and assets explicit, which makes long-term maintenance and distribution easier.
The stack includes a library route, a reader route, and stable public entry points that can be linked and indexed.
